Five-year-old Raul Lara has been brushing his eyes just like cartoon character Spongebob

The account manager has admitted she's not sure how long he's been doing this for as he usually brushes his teeth alone.

However, when she joined him on Monday, July 17, to brush his teeth for the night he told her he had to brush his eyes "so they don't go crusty" but the mum was quick to assure him he didn't need to.

Blanca, from Oklahoma, said: "He told me he had seen Spongebob doing it on TV and he went into the other room and showed me the part where he gets up for the day and puts toothpaste on the toothbrush and brushes his eyes.

"He knows not to clean his eyes with toothpaste, he has common sense in that area.

"He has stopped doing it now, I told him he didn't need to do it. He asked why not and I just told him it would really hurt his eyes if he kept doing it.

"Spongebob is his favourite show. He watches it every day he is a huge fan.

It's not clear how long the little one has been incorporating this into his cleaning routine

The mum uploaded a clip of the youngster demonstrating the eye brushing on social media and wrote: "Usually I just tell him to brush his teeth and go to bed. Today I joined him. This is what happened. Worst part is I don't even know how long he's been doing this."

Blanca said: "I don't think Spongebob [producers] put it out there intentionally hoping kids would copy it. I think kids just see things and think 'oh that's a great idea.'
